- the pawl 148 is disposed in one of a plurality of valleys 121 formed between adjacent spline ribs 120 such that the stopping portion 152 of the pawl abuts a wall portion 123 of a spline rib.
- the illustrated embodiment includes only a single pawl engaged with a single spline rib at a time, other embodiments that include multiple pawls engaged with multiple spline ribs are also contemplated herein.
- the ratchet sleeve 116 When in the locked position, such as in the embodiment shown in FIG. 7 , the ratchet sleeve 116 is prevented from rotating with respect to the mop handle 102 in a first rotational direction 160 , but can be rotated with respect to the mop handle in a second rotational direction 162 . As shown, the angled portion 150 of the pawl 148 can slide against a sloped portion 125 of the spline ribs 120 , allowing rotation of the ratchet sleeve 116 in the second rotational direction 162 .
- a ratcheting effect is possible in which the ratchet sleeve 116 is rotatable about the mop handle 102 in the second rotational direction 162 , such as to tighten the twist mop assembly 112 , and the ratchet sleeve is simultaneously prevented from rotating about the mop handle 102 in the second rotational direction 160 .
- the pawl and spline ribs can instead be configured to allow the ratchet sleeve to rotate in the first rotational direction with respect to the mop handle and to prevent the ratchet sleeve from rotating in the second rotational direction when in the locked position.
- FIG. 8 shows the flexible collar 144 in an unlocked position in which the pawl 148 disengages the spline ribs 120 so as to allow rotation of the ratchet sleeve 116 with respect to the mop handle 102 in both the first and second rotational directions 160 , 162 .
- the flexible collar 144 is flexed from the locked position to the unlocked position when a squeezing force, F, is applied to the tabs 146 .
- the squeezing force F causes the flexible collar 144 in the vicinity of the pawl 148 to bow outward into a substantially ovular shape and pull the pawl out from the valleys 121 between spline ribs 120 .
- the pawl 148 In the unlocked position, the pawl 148 is no longer preventing rotation of the ratchet sleeve 116 with respect to the mop handle 102 in the first direction 160 because the stopping portion 152 of the pawl is now longer abutting the wall portion 123 of any spline ribs 120 .
- the squeezing force F is released from the tabs 146 , the flexible collar 144 is biased back into the locking position.
- the mop head 114 has a first end 166 opposite a second end 168 .
- the first end 166 of the mop head 114 is connected to the mopping end 106 of the mop handle 102
- the second end 168 is connected to the ratchet sleeve 116 .
- the mop head 114 can include a plurality of mop head bands 128 that concentrically surround the mop head to connect the plurality of strands 122 to one another. Although the illustrated embodiment shows three mop head bands 128 , it is contemplated that more or fewer bands can be used in other embodiments. As shown in FIG.
- the second end 168 of the of the mop head 114 fits over the retaining collar 142 on the ratchet sleeve 116 .
- the second end 168 of the mop head 114 can be retained by wire, zip ties, or any other suitable retaining mechanism.
- a plurality of tightening ribs 170 can help secure the mop head in place against the retaining collar 142 .
- the retaining collar 142 prevents the mop head 114 from sliding off of the ratchet sleeve 116 and pulls the second end 168 of the mop head toward the grip end 104 of the mop handle 102 when the ratchet sleeve is pulled toward the grip end. Additionally, the tightening ribs 170 help maintain a tight connection of the second end 168 of the mop head 114 against the ratcheting sleeve 116 so that when the ratcheting sleeve is rotated with respect to the mop handle 102 , the second end of the mop head rotates along with the ratchet sleeve.
- FIG. 5 shows an embodiment of the mop 100 in a wringing position.
- the flexible collar 144 and, thus, the pawl 148 is disposed adjacent the plurality of spline ribs 120 on the spline sleeve 118 .
- the ratchet sleeve 116 can be rotated with respect to the mop handle 102 in the second rotational direction.
- the first end 166 of the mop head 114 is connected to the mopping end 106 of the mop handle and, thus, is substantially stationary with respect to the mop handle, rotating the ratchet sleeve 116 will result in the mop head 114 twisting around the mop handle 102 .
- the plurality of strands 122 in the mop head will constrict against one another in a wringing action that will tend to wring water or other fluids out of the mop head.
- the pawl 148 then prevents the mop head 114 from untwisting itself an adequate squeezing force F is applied to the tabs 146 , disengaging the pawl from the spline ribs 120 and moving the flexible collar 144 into the unlocked position.
- an adequate squeezing force F is applied to the tabs 146 , disengaging the pawl from the spline ribs 120 and moving the flexible collar 144 into the unlocked position.
- the user can rotate the ratchet sleeve 116 with respect to the mop handle to wring the fluid out of the mop head strands 122 .
- the mop When the mop 100 is not in the wringing position, the mop can be moved into a mopping position, such as is shown in FIG. 2 , wherein ratchet sleeve 116 slides down the mop handle 102 such that the flexible collar 144 and the pawl 148 are disposed between the spline sleeve 118 and the mopping end 106 of the mop handle.

- the locking cap 126 has a tab portion 135 and a locking portion 137 separated by a neck portion 139 .
- the neck portion 139 has a substantially smaller diameter than both the tab portion 135 and the locking portion 137 , resulting in a substantially hour-glass shape.
- the locking portion 137 of the locking cap has at least one locking tab 141 projecting radially away from the edges of the locking cap.
- the locking portion 137 of the locking cap 126 can be selectively twisted into the locking cup 124 so that the locking tabs 141 engage with the interior threads 133 of the locking cup, securing the locking cap and the locking cup to one another.
- the tab portion 135 of the locking cap 126 has a twisting tab 143 projecting away from the locking portion 137 that can be used to twist the locking cap into place within the locking cup 124 .
- the first end 166 of the mop head 114 is secured to the locking cap 124 around the neck portion 139 of the locking cap using wire, zip ties, or any other suitable fastening mechanism.
- the mop head 114 is effectively secured to the mop handle 102 via the connection between the locking cap, the locking cup, and the mopping end 106 of the mop handle 102 .
- the strands 122 on the first end 166 of the mop head 114 adjacent the tab portion 135 of the locking cap 126 are squeezed between the tab portion and the interior wall 131 of the locking cup 124 to help secure the mop head in place at the mopping end 106 of the mop handle 102 .
- the action of wringing out the mop head 114 can result in further tightening the locking cap 126 into the locking cup 124 .
- the interior threads 133 of the locking cup 124 are oriented such that the locking cap 126 is rotated in the second rotational direction 162 (as indicated in FIG. 7 ) to tighten the locking cap into the locking cup.
